I am a designer looking for an iOS developer partener. I have an iOS app concept that can be very popular. The project on which we'll be working will be similar to this http://www.youdress.com/app/en/index.html
I know the budget is not much, that's why the programmer of this app will have percentage from sales. Will be a free app, but will have some features that the user needs to buy.
All GUI will be provided by me.
